Hi everybody!
My 15-year old daughter have a LT15a since April this year and eventually she managed somehow to break the USB port about 2 months ago, I don't know how. It was bought in the US like in February by a friend of mine, and besides that I unlocked the bootloader, so warranty claim is not an option.
I was happily using JellySandwich v4.3 and I tried to update to V5. It didn't work but I remember reading that it was based on .587 and I was on .431, so I found a .587 LT15a firmware and began flashing in Flashtool. After it finished, I removed the USB cable and it was the last time the port worked. I knew it was damaged from before, because it only worked with only one of the several microUSB cables that I have (I also own a BB, an X10 and a Milestone) and had to put it in a special position on my PC, It didn't work anywhere else, so I removed the cable very carefully but I failed. I transferred the files I needed via WiFi, trying to use the USB port the least possible. I visited several Cell technicians here in Venezuela, but this phone is almost unknown in here, let alone finding parts for it. Googling, I found the USB port in eBay (several Chinese sites have it and one in UK) but it will take forever to reach here.
After this LOOOONG story, here comes the question: Is there anyway to root it and install CWM without using the USB port? I looked everywhere but didn't find a solution. I even tried the Flashtool ADB restore option, but didn't work
This phone is almost useless without A2SD or Link2SD
Thanks in advance for your answers

Good afternoon all this is a bright Sunday in Halifax Nova Scotia. I would like to first apologize if this is a redundant thread so if anyone sees that my issue has been resolved elsewhere (and yes I have been at this for DAYS) please close this thread and point me to the right direction.
I have a Samsung Galaxy S3 from Rogers model i747M
Everything was working find until I happened to it lol :silly:
I installed ParanoidKANGdroid succesfully, after playing around with it I got a little cocky and tried to install other roms...
After reading up on the best roms for my device I stumbled upon Pardus HD (not realizing is was for the i9300 because I was all excited and didn't read.... just being honest)
So what I did was followed some guide (can't remember which one but if its imporant ill try and find it) to intall clockwork mod via odin. Successful :laugh:
After this I booted up my phone and moved the Pardus rom to my internal sd as directed and loaded into clockwork recovery...
Now the directions mentioned to WIPE DATA AND CACHE so this probably wiped the working rom off my phone.
I then went to install off sd card, found the rom, and installed it, the install errored out and aborted. At this point I was still in recovery and rebooted :crying:.
Now my phone will not turn on, there is literally no life going to it. When I plug it into my pc I do hear a sound but its the sound of a device driver error the driver its looking for is QHSUSB_DLOAD.
What I've tried...
Download mode again (of course it won't work)
Finding that driver (no luck)
connecting some wires to the battery (poor man jtag; unsuccessful)
What I want to try but haven't yet as I don't want to mess it up further....
jtag (since I don't have it)
sd card trick to install bootloader (scared to mess it up) this seems the most promising but cant find the guide to me particular model
sd card trick using another working phone same model (don't want to mess up someone elses phone)
I would like to try every option other than sending it off before that ends up being my last resort.
Any help would be great appreciated. I thank you in advance.
Did you make the jig and try it yet? Cause that might be the last resort before sending it off...good luck bud!

So this may not seem as simple as it looks. my question is, is my phone hardbricked or softbricked? (just to be clear there is NO life, no led, no download mode, no charging, just QHSUSB_DLOAD when connecting to pc for which i dont have drivers) will this work in either situation?
Thank you so much for the help so far, i assure that i will most my journey and success with every step once i have this figured out. thanx again
I'm pretty sure it is that simple...jig worked great on my captivate and 1st Gen note both hardbricked....making and using the jig can't hurt you at all...try it and see.

my mistake was i chopped a blackberry data cable. found an original samsung one, chopped it, rigged it up, it works on a good s3 (friends) boots it right into download mode so the jig is working now. i will post on how i made it and what youtube video i followed later. however the jig isnt working on my s3. but i found a [email protected] pdf doc from samsung on how to use another s3 to flash bootloader. just need to find i747 boot recovery image and hopefully i can use his s3 to resurrect mine... any ideas on that method?
This issue has been solved!!! YAY
Okay ladies and gentlemen so my issue has been solved!
Here's how I fixed my issue!
I disassembled the phone I connected a Jig that I learned how to make through mobile tech videos, I then connected an external power supply by attaching two prongs to the positive and negative battery terminal at 3.7 mah, Then I shorted with a pair of tweezers the R 313 chip on the back of the motherboard of the phone. After a few tries download mode came up I disconnected the jig reconnected it and somehow the download counter reset.
Up and running on stock Rogers I 747M 4.1.1 Rom
If you buy your jig on Amazon for about $25 usually those ones actually come with a power supply port On the back of them so you don't have to actually hookup an external one. I'm not sure exactly what the purpose of the R313 chip is I found a leaked Samsung Tech service manual online to do this. That manual also asked for another S3 in working order to be part of the equation to force load a boot loader and then reflash to T flash However jumping the gun in this matter it actually worked if I'm lucky I'm happy if this is how it was supposed to work I hope I really helped someone. Thank you all for your help so far! :laugh:
where on the board do you find th R313 chip. how did you know to rcognize it. Is the rogers mother board the same as the atnt i747

thanks for information you upload about your experience.
would you please let me know where is R313 is located on i747M main board,as I have the exactly same problem.
any help would be appreciated.
QHSUSB-DLOAD Stands for Qualcomm High Speed USB Download Mode.
This means your motherboard can't find working drivers to run, so it will try to boot from somewhere else.
(Which is the SDcard)
To put the sdcard with bootloader info is safe. Its like putting a CD into your computer, it won't make any changes unless its asked to change the harddrive.
Here is a T-Mobile thread that did it: http://forum.xda-developers.com/showthread.php?t=2439367
Here is the i747m image (only works if you didn't update to 4.3 from an OTA from phone company)

do you still know how to flash clockwork mod on the phone I have the I747 But the AT&T model from what I have heard the GS3's use the same process just different boot loaders
Also I did kind of the same thing with my phone but instead of flashing a rom I tryed to unlock a boot loader that was already unlocked and was for a different model lol :silly: .
I already know how to fix it I just need the Debrick img for the SDcard trick where you put the boot loader on the card it self
If you have seen the I747 At&t vision debrick img can you tell me?
I have the sdcard trick here http://forum.xda-developers.com/showthread.php?t=2549068 if you still need it it even has the debrick img for the I747M

Hi,I'mhaving the same problem you're having but can't seem to locate the R313 chip on the board. I got the i9300 leaked guide for the shorting but I can't locate the R313 can you please tell me where to look? thanks.

If you still alive can you refer to the r313.
thanks in advance.
They said it was from a leaked guide for the i9300, so there's a very good chance the Qualcomm devices fo not have it. They are very different devices and use entirely different SoC's, do it would make sense that the rest of the hardware would also be different.
Not saying its not worth looking into, just that its a good possibility since no one else seems able to find it.

yesterday was trying this method but didnot success. I find my lost usb JIG. and will try with external power supply.
I will test more when I have time to unbrick my SCH-I535 and may this way leed to unlock our devices.
Hey Everyone
I've been looking around the site (and the rest of the web for that matter) and I can't find much on this that's helpful (at least not anymore).
I used to flash custom shizz on my phone regularly until I flashed back to stock for a while, and now I've decided to go back. The problem is, my USB port broke in the mean-time and I can no longer plug it in I know I could buy a new USB port, but it's a lot of work for a phone that I'm only going to be using for a couple more months (will be upgrading to the S5)
Is anyone aware of a way to root on the phone itself? So far I've tried http://forum.xda-developers.com/showthread.php?t=2352669 and Framaroot to no avail - I can't find anything else.
Any help would be massively appreciated.
Thanks!
Greetings, i have my t989 rooted with 4.1.2 original rom. It was with that version when i got it yesterday and then i root it and change the rom to 4.0.3 just to unlock for free without any problem. I return to 4.1.2 after all and root it all good until i want to transfer something to my phone and now the phone disconect from computer. I try many cables and then plugged it to a wall charger and it was not.charging then i clean the charging port of my phone and it started to work great but again it started with the same problem.
May the problem be the root? Or i just damage my new phone? It looks almost new and as i said i could install all the thing until root it.
Could you help me?

I would flash a different rom and see if it works then.. Also check all your settings Usb debug etc... Defentily try different roms if it don't work on multiple other roms then it could lead you to believe its hardware related...Hit thanks if this helped. If you have any other issues then message me
I just take it to a rep and fic the problem. It seems like the usb got a problem. Thanks

I am at my wits end to try to repair my phone. It is softbricked and responds to download mode only.
I've had chat with xda members and read threads on it:
http://forum.xda-developers.com/chef-central/android/nand-write-start-fail-odin-soluction-t2851096
http://forum.xda-developers.com/galaxy-note-10-1/help/help-help-unbricking-galaxy-note-10-1-t2872125
and many others. in the end, my phone is still stuck with the NAND Write Start error with odin.
I know it happened after i tried creating a backup of my phone in recovery mode (phone was rooted with cf auto root and had a version of CWM on it). CWM gave me a warning about possibly bricking the phone, i agreed to the warning beacuse it always worked in the past, but when i rebooted, it was bricked this time.
this phone is not dead but samsung won't fix it beacuse it is rooted. I refuse to throw it away. I have read many people have it this error since kitkat 4.4 so surely there is a fix somewhere. I am hoping somebody will be more resourceful/experienced than i am.
I have tried changing to several different USB ports, without a hub, using original cables (bunch of different ones too) in many many different order and fashion. I tried enough variation to be convinced it is statistically impossible that all my hardware that was previously working for flashing has stopped working all at once. aka - it is not a usb port or data cable problem
may be related to data charging port on the phone though I highly suspect it given how it started.
I tried different roms, different versions of odin, i tried depackaging and repackaging roms, i simply do not know what to do anymore.
i tried reflashing with kies but kies just dies on me.
i tried flashing it with adb but adb won't even connect. when i plug the phone windows recognizes it and usb driver seems to work ok (not getting an error)
I have uninstalled and reinstalled drivers several times, rebooting in between installs. no difference.
i tried flashing different bootloaders as well as entire roms, no difference
I tried changing the pit file but that failed as well (odin couldn't even write the pit so my phone is not dead even if i failed pitting it)
i have access to both windows and ubuntu linux if it makes a difference.
Here are the terms of the bounty:
Price : 100$ (payable by paypal from eniac0 @ "some google mail domain starting with gm"
goal : find a fix that works on the latest firmware for SGH-i317M (Rogers, Canada)
how : i don't know but i need to be able to reproduce it. I am not new to flashing but anything advanced will need to be explained clearly.
I don't really know how this sorts of request usually turns out but i am serious. you even got my google mail address to bill me up if i fail to pay.
have you given a look at this thread? http://forum.xda-developers.com/showthread.php?t=2711825 it might give you some ideas to help you out. also did you try flashing a new recovery to see if you could at least get it to boot to that?
dont care about the bounty just trying to toss something out there that may help you
Did you ever try flashing the stock recovery - JUST the stock recovery - through Odin?
If not, grab the recovery.img and make your own tarball for Odin in Linux.
Hopefully that will flash and get you closer.

Since you mentioned Ubuntu, you can also try using heimdall instead of odin... http://glassechidna.com.au/heimdall/ . Unfortunately, I think it may be a hardware problem?
Since you are willing to pay to have it fixed, if all else fails, you can always send it off to http://mobiletechvideos.mybigcommerce.com/samsung-galaxy-note-jtag-brick-repair/. It will actually be cheaper than what you are offering to pay ~$40 + shipping
good luck
Thanks all for your help, I've messed around and gotten no closer. I'm beginning to lean on a hardware failure, perhaps from the usb data port either that or the way bootloaders are packaged in kitkat 4.4 is different. which is why initially this thread gave me hope: http://forum.xda-developers.com/chef-central/android/nand-write-start-fail-odin-soluction-t2851096 but i tried far too many times now to believe I'm going to succeed. In fact, I've gotten confused as to what i tried, in which order, with which rom. I'm basically trying anything and that's a recipe for bricking the phone for good. so i've stopped.
I'll also thank kozmo21 for the link to the repair shop. i was unaware this existed, as a last resort I'll be sending them my phone. If it turns out they are able to repair it, I'll honor my word and give you something for having been part of the solution.

Have you tried going to sammobile and download the newest firmware and only flashing that in odin?
Use CF auto root. Put the phone in download mode and flash it in Odin. I soft bricked my phone and it fixed it.
Also this guy had great walk through videos on how to do everything you need.

More than likely its a bootloader issue my phone did that and all i did was flash the bootloader then it worked again but hes done so much idk what he needs now that's y i said to try a firmware to see if that helps
Download toolkit and select option to push file into phone.
Download a ROM of your choosing, push it into your phone, restart in recovery mode and select file.
Update?
Did you get it fixed? Just my two cents, in case you didnt, I had a similar problem and alll I did to fix it was flash the JediMasterX2 ROM with CWM and everything worked out.
Hi all. I'm posting here because after countless (2) hours of searching online I haven't been able to find a proper solution for a problem. I'm hoping that you all can help me with this one.
I've been using the LG g3 for the past year and everything has been great. But since my screen got smashed I've had to replace it with a newer one. I got this last Thursday.
I've been sticking with stock because I'm quite fond of the stock marshmallow. But since I'm a tinkerer I can't help myself. So after I updated (yesterday) I was going to attempt to root and flash a shiny new rom. Unfortunately, I haven't been able to get that far, as my phone can no longer be recognized by my computer.
I will put it in, and it will pop up with "USB Device not recognized". Under device managers it merely shows up as "unknown usb device". So I uninstalled my LG drivers (which are normally installed once you plug in the phone, but I digress. It did all of this before the 6.0 update) and it will attempt to install usb drivers but fail almost immediately and say it experienced an "unknown error", very helpfully reminding me to try and unplug/plug the device or factory reset.
Factory reset is very difficult for me right now as I have just finally gotten the phone tweaked to my liking. I really don't want to have to re-download everything. I have tried almost every workarounds I could find on the Internet but I keep running in circles. I've downloaded several different drivers for my phone and none of them work. I'm really at a loss.
I'm assuming that it must be the marshmallow update, as I haven't rooted or installed cfw as of yet. And I can plug someone else's phone in and it will install the drivers in a heartbeat. I can charge my phone but it won't give me options for MTP/PTP/Charge mode at all.
Anyways that's about all I can ask at the moment. I just hope someone here has experienced this and knows what to do.
Okay, I have now tried factory resetting my phone and it still won't work. It's the 6.0 update that's causing this. I'm at a loss, either I have to wait for google to hopefully patch this or I have to take back my new phone and exchange it for a new one.
You should be aware that the correct model number for a Canadian G3 from Koodo is D852, not D820 as you mentioned.
Before taking back your phone, try to see if your phone is recognized with a different USB cable (OEM one preferred), plugged in a different USB port of your computer, or, if possible on a friend's Windows 10 or Windows 8 computer, just in case different drivers might recognize your phone.
Your suspicion (that the OTA update to MM caused this) is not well supported by the reality: the OTA update was quite uneventful for thousands of other Canadian G3 phones; we should have heard more complaints if the OTA update were botched by Koodo or Telus.
